Workplace competency assessment solutions for personal and professional development are used across Africa. These solutions can be very valuable for companies and individuals, if they are applied correctly. From my experience I know that this is not the case. None of the solutions I found, take into account the African culture and the development context in their design. We therefore have to challenge the assumptions behind the tools, their application and results.

Na-zanga is a given name from the Mambwe people in the Northern province of Zambia; it means to discover or to find the solution, to what you have been seeking.

Zanga African Metrics uses technology to develop online human capital development solutions that are adapted to the African culture and context, thereby increasing the relevance, impact and sustainability of the results. Our solutions are scalable across businesses, and countries.

We join forces with those at the frontline of innovation in Africa; those who are realizing the development aspiration for the continent and its people. 


To support wealth creation across African generations.


  1. Ubuntu – I am because you are, you are because I am.

  2. Purpose – I was created to respond to a need in the world for my generation.

  3. Professionalism – I do my best and I do it well.

  4. Passionate – I believe in and enjoy what I do.

  5. Life learner – I am always learning and co-creating my success.

  6. Integrity – I do what’s right irrespective of the consequences.


Zanga African Metrics is a Zambian, female-owned specialized company in the design and development of human capital development solutions for success in Africa. We use cultural and  behavioural insights to reflect how people actually make decisions and act on them in an African context. To develop our solutions, we drew inspiration from many African and international thought leaders.


Our team brings together a powerful partnership with over 50 years of combined experience in leadership development, entrepreneurship, industrial psychology and national development in Zambia, Africa and internationally; in both the private and public sectors.


We thank the world's #1 Coach and Educator, Dr. Marshall Goldsmith, and the Marshall Goldsmith Knowledge Philanthropy Project, for inspiring us and giving us permission to adapt and use his work, including the "6 Daily Questions," in our Self-Coaching App.
